Purpose: Marital dissatisfaction and conflict often increase for couples after the birth of a child and are evident in fewer positive family interactions and more negative family interactions. Because exercise is known to increase positive emotions and decrease negative emotions, the current study examined the extent to which higher levels of mothers’ exercise during the postpartum period were related to more positive and fewer negative emotion-expressive behaviors with their infants’ fathers. Method: Mothers’ (N = 46; M = 8 months postpartum) positive and negative expressive behaviors were coded during couples’ discussions of current conflict and positive family experiences. Mothers self-reported their leisure-time exercise behavior. Results: First-time mothers and mothers with higher levels of leisure-time exercise behavior displayed higher levels of positive expressive behaviors during couples’ discussions. Conclusions: Exercise may be associated with increased positive emotion and, in turn, can have great potential to improve family relationships during the postpartum period when marital stress normatively increases, particularly for mothers with more than 1 child. Future longitudinal studies are needed to understand exercise patterns across the postpartum period to identify the most effective timing and optimal level of exercise that lead to more positive expressive behaviors. 相似文献

Do physical activity beliefs differ by age and gender? 总被引:1,自引:0,他引:1
Age and gender are consistently related to physical activity (PA), yet theoretical explanation for these associations is scant. The present study compared the mean values and correlations of a population sample, divided by gender and age group, with respect to theory of planned behavior beliefs (behavioral, normative, and control) and PA. Participants were a sample (N=6,739) of adults (M age=49.65, SD=16.04) who completed measures of social and health demographics, theory of planned behavior beliefs, and self-reported PA. Mean analyses identified greater perceived control over PA for seniors than for young and middle-aged adults (N>.025). Belief-behavior correlations, however, were not different across age and gender in 24 of 26 tests (q<.19). Thus, PA beliefs are invariant across age and gender with the exception of mean levels of perceived control, which are lower among younger adults than older adults. Factors such as early parenthood and career demands were considered the likely reasons for differences. Overall, the evidence suggests that adapting theoretical models for specific age groups or based on gender may not be necessary. 相似文献

In an effort to establish a baseline of technology competency among our entering education students, our College of Education began implementing the Assessment of Technology Competencies (ATC) in Fall 2003. This performance-based assessment evaluates word-processing, presentation, spreadsheet, graphic/drawing, and Internet skills. Although students are not required to pass the ATC, failure impacts their final grade in an Introduction to Education course. This paper explores the impact this assessment has had on the students' use and development of technology in subsequent courses. Student perceptions of the ATC and its impact were elicited through a self-reported survey administered in a junior-level education course. Results indicate that the ATC has facilitated technology use among the participants. Respondents also revealed that their high school experiences with technology adequately prepared them for passing the ATC, despite the fact that most students are unable to pass the ATC in the first attempt. 相似文献

The main function of agricultural extension is generally thought to be the transfer through nonformal educational means of practical knowledge to agriculture and the enhancement of rural development. Agricultural extension has received renewed attention in recent years from international development agencies and considerable discussion has ensued regarding the appropriate role for extension programmes. Much of the attention has been directed towards improving the functions of existing services. This article discusses the policy considerations of extension within the broader context of agricultural development goals and the overall direction of the country's development objectives and strategies. A framework is presented for analysing important characteristics of different extension development options. The issues raised are relevant to the larger concerns of adult education policy and the promotion of lifelong learning strategies within society. They include the relationship of sectoral goals and policies to broader national objectives, the audience the public sector should target, the role of the private sector, the structural arrangements best suited to meet certain objectives and the correct mixture and co‐ordination of various services and programmes. 相似文献
